1-1 Product features

■ Double-acting type cylinder(1) The cylinder space which is enclosed by the case ① and the

covers ⑥ and ⑦ is divided into airtight chambers ⓐ and ⓑ by the pistons ⑤ and the piston packing ㉔.

(2) The shaft ② penetrates the chamber ⓑ of the case. The yoke ③ is fitted in the hole across the shaft in such a way that it allows it to slide in the hole. The top of the yoke is connected with the parallel pins 32 so it rotates in accordance with the movement of the pistons.

(3) The compressed air enters chamber ⓐ through port A and pushes the pistons. The air in chamber ⓑ is exhausted through port B as the pistons move due to a pressure difference between the two chambers. Integrated with these pistons, the parallel pins 32 also move and torque in the shaft is generated.

■ Single-acting type cylinder(1) The cylinder space which is enclosed by the case ① and the

covers ⑥ and ⑦ is divided into airtight chambers ⓐ and ⓑ by the pistons ⑤ and the piston packing ㉔.

(2) The shaft ② penetrates the chamber ⓑ of the case. The yoke ③ is fitted in the hole across the shaft in such a way that it allows it to slide in the hole. The top of the yoke is connected with the parallel pins 32 so it rotates in accordance with the movement of the pistons.

(3) The compressed air enters chamber ⓑ through port B and pushes the pistons. The air in chamber ⓐ is exhausted through port C as the pistons ⑤ move and the spring 42 is squeezed due to a pressure difference between the two chambers. Integrated with these pistons ⑤, the parallel pins 32 also move and torque in the shaft is generated.

(4) When air supply to Port B is stopped, the pistons are pushed back due to the force of the spring 42 and torque in the shaft is generated.

1-2 Operating principle

This product is a pneumatic rotary actuator driven by pneumatic pressure of 0.4 to 0.7 MPa for the purpose of actuating a 90˚ butterfly valve. The case is of aluminum alloy which is fabricated by means of extrusion. This manu-facturing method enables the cylinder to be light weight, compact in design and highly accurate. The attachment installation member complies with the NAMUR standard. NAMUR standard attachment parts can be installed directly.

5-2 Single-acting type cylinder side cover disassembly procedure

[Fig. 23]

[Fig. 24]

[Fig. 25]

When taking out the side covers of single-acting type cylinders for disassembly, the internal spring may fly out, resulting in a dangerous situation. When disassembly is required, follow the instructions given below for safe work. For the actuator type T750S, the spring length has been returned to the free length when taking out the standard bolts.

1) Take out pneumatic pipelines from this product, and check that internal compressed air, etc. is discharged completely from this product.

2) Make sure that no damage, such as cracks, deformation and chipping, is noticed on the covers (Cover 1 ⑥, Cover 2 ⑦). If any damage is noticed, stop work and replace the whole actuator because the actuator is dangerous.

3) During work, be careful to avoid workers standing on the extension of the longitudinal direction line of the cylinder until the spring is taken out as a precaution.

4) Please prepare two bolts for disassembly with the size shown in [Table 7] (Not required for T750S.)

5) Take out two diagonally-mounted the "hexagon socket head cap screws ⓑ and ⓓ" [Fig. 23] (Not required for T750S.)

6) Apply grease to the thread part of the prepared "bolts for disassembly", insert them to the holes where the "hexa-gon socket head cap screws ⓑ and ⓓ” have been taken out. Then screw in the bolts to the length shown in [Table 8] and tighten them. [Fig. 23] (Not required for T750S.)

7) Loosen the "hexagon socket head cap screws ⓐ and ⓒ" alternately. When the cover and the "bolts for disassem-bly ⓑ and ⓓ" make contact, loosen all the bolts in diagonal sequence evenly and alternately. [Fig. 24]

8) When the dimension A in the figure is the length of [Table 9], the "hexagon socket head cap screws ⓐ and ⓒ" which are not replaced will come out. [Fig. 25] (Not required for T750S.)

9) Loosen the rest two "bolts for disassembly ⓑ, ⓓ" evenly and alternately. (Not required for T750S.)

10) When the bolts for disassembly (standard bolts in the case of T750S) come off, the spring is stretched fully. Thus the side cover can be taken out safely.

11) Take out the side cover and the spring 42 straight away.12) Take out the side cover at the opposite side in the same

(8) Before inserting the piston ⑤ ASSY into the case , apply grease (lithium soap-base, consis-tency No.2) to the sliding area of the piston ⑤, the inner surface of the case ①, and the bearing outer surface.

Apply grease (MOLYKOTE G paste grease) to the yoke U groove. Please use the application amount shown in [Table 11].

(9) Place the case ① and the piston ⑤ in the direc-tion shown in [Fig. 33]. Be careful of the direction because assembly direction of the piston is different between pressure-opening (7G) and pressure-closing (7F) of single-acting type cylin-ders. Make sure that parts are installed in the direction shown in [Fig. 33] when the cylinder is seen from the top. [Fig. 32][Fig. 33]

(10) Insert the pistons ⑤ into the right and left sides of the case ①.

Align the parallel pins 32 right and left on the pistons ⑤ with the U grooves on the yoke ③. Then insert the shaft while turning the shaft in the direction of the arrow.

After assembly, turn the shaft to ensure the free movement of the piston. [Fig. 33]

• Insert the connecting pin ㉚ after making sure that the pin hole of the yoke ③and the pin hole of the shaft ② are aligned.

• Insert the connecting pin ㉚ into the tapped hole of the yoke ③. [Fig. 31]

Assembly direction of the piston ⑤ ASSY for pressure-opening single-acting type cylinder is different from that of pressure-closing. Assembly with wrong direction causes defective operation, such as reverse opening/closing operation of the valve.

Align the parallel pin 32 that is the part of the piston with the U-shaped notch on the yoke. Match with the shaft rotation and push it in.

[Fig. 33](6) Apply grease (lithium soap-base, consistency

No.2) to the groove of the piston ⑤ and the piston packing ㉔. Please use the application amount shown in [Table 10].

(7) Install the piston packing ㉔ and the wear ring ⑰ to the piston ⑤.

(8) Before inserting the piston ⑤ ASSY into the case , apply grease (lithium soap-base, consis-tency No.2) to the sliding area of the piston ⑤, the inner surface of the case ①, and the bearing outer surface.

Apply grease (MOLYKOTE G paste grease) to the yoke U groove. Please use the application amount shown in [Table 11].

(9) Place the case ① and the piston ⑤ in the direc-tion shown in [Fig. 33]. Be careful of the direction because assembly direction of the piston is different between pressure-opening (7G) and pressure-closing (7F) of single-acting type cylin-ders. Make sure that parts are installed in the direction shown in [Fig. 33] when the cylinder is seen from the top. [Fig. 32][Fig. 33]

(10) Insert the pistons ⑤ into the right and left sides of the case ①.

Align the parallel pins 32 right and left on the pistons ⑤ with the U grooves on the yoke ③. Then insert the shaft while turning the shaft in the direction of the arrow.

After assembly, turn the shaft to ensure the free movement of the piston. [Fig. 33]

• Insert the connecting pin ㉚ after making sure that the pin hole of the yoke ③and the pin hole of the shaft ② are aligned.

• Insert the connecting pin ㉚ into the tapped hole of the yoke ③. [Fig. 31]

Assembly direction of the piston ⑤ ASSY for pressure-opening single-acting type cylinder is different from that of pressure-closing. Assembly with wrong direction causes defective operation, such as reverse opening/closing operation of the valve.

Align the parallel pin 32 that is the part of the piston with the U-shaped notch on the yoke. Match with the shaft rotation and push it in.
